I've installed https://www.itefix.no/i2/content/copssh-free-personal-edition
. Running a shell script the command
if ! "$basedir/grep" -qf "$mydir/$file_with_string"
" ; then
gives the error
Bin grep.exe: error while loading shared libraries: cygpcre-1.dll cannot open shared object file: No such file or directory.
The file cygpcre-1.dll is missing in the bin folder of that ssh implementation. Also, cygcheck is not part of this installation.
